BUILT-Ul? SIDE FRAME.

Application led May 6, 1915.

To all whom t may concern.'

Be it known that I, CARL E. BAUER, a citizen of the United States, and resident of Hammond, in the county of Iiake and State of Indiana, have invented certain new and useful Improvements in Built-Up Side Frames, of which the following is a specification.

My invention relates to railway car trucks and has particular reference to a novel builtup side frame.

An object in the construction of side frames for car trucks is to provide a light,

rigid and economical structure. The element of rigidity is best secured in a steel casting but the weight and cost are `greater than in structures utilizing rolled or pressed metal elements. An object therefore is to so combine certain rolled or pressed metal sections as to secure the greatest efficiency for the weight.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is a side elevation of' a side frame constructed in accordance with my invention; Fig. 2 is a plan view partly in section; Fig. 3 is a section on the line 3w3 of Fig. 1 and Fig. 4 is a section on the line 4-4 of Fig. 1.

Referring more particularly to the drawings it will be seen that I provide a compression member l-l-shaped in cross section as indicated-in dotted lilies in Fig. 3, the top sition while at the point above the journal boxes', as indicated in Fig. 4, the top flanges 10, are in a vertical position whereas the bottom flanges 11, are bent inwardly. At that point rivets 12, are passed through the flanges 10, and the walls of the tension member and rivets 18, are passed through both the web and the inturned flanges 11 of the compression member and the web of the tension member. The tension member consists of a commercial channel which is bent backward, into U-shape to form a web 14, vertical flanges 15, and horizontal flanges 16. This will be understood from Fig. 3, in which the original shape of the channel is Specification of Letters Patent.

indicated in dotted lines. This results in extreme ,strength both in vertical and horizontal directions. The same construction is used above the journal boxes except that the flanges 16, are sheared ofi' for the reason that great transverse strength is not needed at that point. rIhe struts, as shown in Fig. 2, are likewise of l-l-section, the web 17, being terminated at the bottom at the point 18, and at the top at the point 19. The flanges 20, 21, of the l'l are continued beyond the end of the web both at the top and bottom and are bent laterally and secured to the webs of the tension and compression members by suitable rivets. Vearingplates 22, may be secured to the inside faces of the angular struts near the upper ends thereof. As a further reinforcement and as a brake hanger bracket I provide the triangular filler 23, located between the compression member and the upper end of each strut, this mem ber being suitably riveted to the faces of the contiguous parts. As a tic rodfomr the lower portion of the journal box I provide the bar 2l, the ends of which are split and bent in opposite directions thereafter being secured by means of rivets 25, to the web 11, of the tension member.

A side frame constructed as described will be found to be light in weight and extremely rigid; the disposition of the metal is such that the greatest strength isrrsecured by the use of a minimum vfeight.

I claim:

1. In a side frame, a compression member, tension member and struts, said com* pression member being of H-form in cross section. the flanges thereof being bent into horizontal position at a point midway of the length of the member, substantially as described.

2. In a side frame, the combination of a compression member, tension member and struts, said compression member being of original H-form in cross section and said tension member being of channel shape in cross section. substantiallyT as described.

3. In a side frame. the combination of compression member, tension member and struts, said compression member being of ll-l-form in cross section and said tension member being of channel form, a plurality of flanges of the compression member being bent in a horizontal position at a point midway of the length thereof, substantially as described.

4. In a side frame, the combination of compression member, tension member and struts, said compression member being of H-shape in cross section, the member being positioned with its web in a horizontal position, a plurality of the flanges of said member being bent into horizontal position at a point midway of the length of the member, and certain anges of said member at the ends thereof being inturned, substantially as described. Y

5. In a side frame, the combination of compression member, tension member and struts, said tension member being composed of a channel the edge portions of which are bent backward to form a deep channel having lateral flanges the ends of the compression member being seated in and rigidly secured to the Web of said deep channel, substantially as described.

6. In a side frame, the combination of a compression member of original H-shape, a

tension member of channel shape, and struts of H-shape, the parts being secured together V described.

7. In a side frame, the combination of compression member, tension member, and struts, said struts being composed of H- shapes the flanges of whioh'are longer than the Web thereof, which flanges act as attaching means between the struts and the compression and tension members, substantially as described.

8. In a side frame, the combination of compression member, tension member and struts, .said compression member being of H-form, a plurality of the flanges thereof being bent into horizontal position both at the middle and the ends thereof, said tension member being in the form of a deep channel having lateral flanges, substantially as-described.
